Re: [WIRELESS-LAN] ArubaOS 8.5.0.7
So with 802.11AX turned off on our 515's hoping for maximum stability and good user experience, it sounds like 8.5 is exactly where we want to be with hopes that it leads into a new conservative release, and that a conservative release of 8.6 happens before we have lots of AX clients and really want to enable their AX capabilities.

Chromecast on Residence Hall Network
Does anyone have a good solution for managing student Chromecasts on their residence hall network? The problem that we're running into is that I think there is some limit to the number of chromecasts that will appear on the list when you try to select a device to cast to. The result is that some students can see their chromecast, but other people can just see a bunch of other chromecasts but theirs is not on the list. We are transitioning from an HP MSM wireless network to an Aruba wireless network. This problem is getting worse over time as we move to more Aruba AP's because the MSM's were configured with a separate wireless subnet for each building. That limited the number of chromecasts on each network and increased a user's chance of seeing theirs. As we move to Aruba, all of traffic is tunneled back to the controller and all of the users are on a single subnet. An elegant solution is to us ClearPass as the NAC for the network and then let users set up their own Air Groups then their devices see each other and no one else's. This also solves the problem that there is nothing preventing one user from streaming to another user's chromecast. We use Bradford Networks Network Sentry as our NAC, however, and switching to a different NAC isn't in the cards as a near term solution anyway. Network sentry doesn't provide any way to manage air groups. When we first set up our Aruba controller the chromecast traffic was blocked by default, and I worked with support to get an Air group set up tohave that traffic sent everywhere. I was wishing for some way to make an air group per building or per some group of AP's that we'd create. That would mimic the imperfect but better solution that we've had with our MSM AP's. Support couldn't seem to come up with that sort of a solution for me. I'm not sure if that's not possible, or if I simply should have kept escalating the ticket until I found someone that could help make that configuration. I'm wondering if any other Aruba users out there have found a solution to this issue that doesn't involve also being Clear Pass customers. -- *Adam Forsyth* Director of Network and Systems Luther College Information Technology Services *700 College DriveDecorah, IA 52101563-387-1402* ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.

Re: [WIRELESS-LAN] Measuring RADIUS Performance
We have Network Sentry as our NAC rather than Clearpass, but I think what you're saying might apply anyway. So on any given day multiple somebody's 180 Days have come up, and our system will force them to change their password. They have some number of devices that they've used their username and password to connect to our 802.1x SSID. The minute they change their password those devices are going to start failing to log in. Even if they have meticulously kept list of the devices that need to be told their new password for connecting to wireless and immediately proceeded to update those, there'd be multple failed logins from their devices. The more likely scenario is several days later they're thinking I should really look into why my phone doesn't seem to connect to the wireless network anymore.oh well it can still connect to the cellular data. I can't do anything about how many users have clients configured with old passwords in them, so does that make Clarity's tabulation of RADIUS authentication time useless to me?

Measuring RADIUS Performance
How do you measure the performance of your RADIUS Serve? How fast is fast enough? How slow is unacceptable? We have Aruba Airwave, and its Clarity module provides me a way to measure the amount of time that RADIUS Authentication takes. For our RADIUS MAC SSID's it says it takes 63ms, and for our 802.1x SSID it says 2392ms. The settings Airwave comes with by default are that <500ms is marked green meaning good, 500 -- 1000ms is marked yellow meaning warning and >1000ms is marked read meaning poor. Of course faster is always better, but I wondered if others have opinions on whether Airwave's ranges are reasonable, or whether they have unrealisticly expectations. If they're reasonable, then I probably need to figure out how to speed up our 802.1x RADIUS performance. -- *Adam Forsyth* Director of Network and Systems Luther College Information Technology Services *700 College DriveDecorah, IA 52101563-387-1402* ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
Re: [WIRELESS-LAN] Bandwidth/Throughput/Latency Tester
Isn't this: https://www.ookla.com/speedtest-custom what you asked Ookla about and were told that it doesn't exist? I ran a version of that on a local server a few years ago.I got the premium subscription for a year but ultimately decided I hadn't figured out how to get any advantage from its ability to save test results into a database. I have since moved to using https://github.com/adolfintel/speedtest (which Clemson also mentioned) because I wanted a speedtest that was HTML5 and didn't use flash, and at the time Ookla's speedtest custom required flash. It looks like maybe its also all HTML5 now so maybe I'll take a look at that again.

Re: [WIRELESS-LAN] Wireless to Wired Bridge
Can it be configured as a bridge without repeating the wireless signal? I bought a VONETS VRP5G to try before recommending a solution to the student. Maybe I haven't played with it enough yet, but my issue with it is that it really seems to want to repeat the wireless signal and be a range extender in addition to a bridge.

Re: [WIRELESS-LAN] Wireless to Wired Bridge
For a laptop or a desktop I agree. For this current application, the wired only device is a blue-ray player, so it's not going to work with a usb adaptor.

Re: [WIRELESS-LAN] Disabling LEDs on APs
We turn them off where we have the traditional ceiling mounted AP's located in student rooms. I wish they had an option to leave the power LED on, but not have other LED's blink for network traffic. My opinion is that the flashing lights would be annoying to me on the ceiling of a room I was living in, but the solid power light would be no different than a little light coming in through the window or under the door. That would avoid the occasional trouble ticket where someone happens to notice that AP's in classrooms have flashing lights and the one in their room doesn't, therefore the one in their room must be broken. This summer we installed Aruba AP-205H's in student rooms in 2 residence halls. The lights on those are small enough and dim enough that I decided not to mess with them and have left them on. So far I've not gotten any complaints, so either I'm right that they're small enough not to be annoying, or students are self solving the problem with tape or post-it notes, etc. On Tue, Sep 6, 2016 at 8:57 AM, Lee H Badman wrote: > First-world problems… Curious if others have gone down this road in > Residence Halls.

Re: [WIRELESS-LAN] 802.11b data rates disabled?
Wii is the most mentioned issue that people are mentioning that they encountered with turning off B rates (and that's the one I've feared and has made me hesitant to do this on our network). Using a wired port instead is sometimes mentioned as a work around but that doesn't work for us in two of our residence halls that are wireless only and don't have wired ports. For those that have wireless only residence halls and have disabled B rates, do you just say Wii's are not supported and there is no work around? Also, I don't think they have sold many of them, but does any one know if the Wii U solved this problem of B rates being required or if it has the same problem?

Google Chromecast
Have any of you had a chance to play with the Google Chromecast and thought about what issues it might create for wireless in residence halls when students bringing them back to school with them and connect them to the network? Its broadcasts an SSID when it's first connected for setup. Like wireless printers my assumption was that this would create interference with our 2.4Ghz network until the student finishes setting up the chromecast. After that the SSID goes away, and so should the interference.at least that's what I thought until I was using inSSIDer this afternoon at home, and noticed that I saw an SSID called Livingroom Chromecast (That's the name of my chromecast at home). The SSID was there for a few minutes and then went away again. Maybe 20-30 minutes later, I saw it show up again for a few minutes and then go away. I can't imagine what its trying to accomplish with this behavior. Anyone have any insights? My original thinking was that we'd need to make sure that chromecasts got set up and weren't plugged in and left unconfigured, but that after that they wouldn't cause wireless network problems. Watching this rogue ssid come and go, makes me wonder if we're headed for disaster if lots of students have chromecasts. Moving from the realm of technological problems to people problems, I think students may annoy each other by playing media to the tv's of others. There's no password or prompt to stop it, whoever requests to send a stream to the tv last sends their stream to the tv. -- *Adam Forsyth* Director of Network and Systems Luther College Library and Information Services * 700 College Drive Decorah, IA 52101 563-387-1402 * ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Powerline ethernet as uplink to an outdoor access point
Has anyone tried to use a powerline ethernet product as a backhaul to an outdoor wireless access point? The thought crossed my mind today that that might be a possibility. The remote AP can be powered by a light pole and electrical service to that light comes from a breaker inside one of our buildings. If the uplink came from the same place the power does, that would make the installation a lot simpler I think. Now that I've had the idea, I wonder...is this a good idea or a bad idea? -- *Adam Forsyth* Director of Network and Systems Luther College Library and Information Services * 700 College Drive Decorah, IA 52101 563-387-1402 * ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Disabling 802.11b speeds
I like that idea, and I wouldn't have thought of it, but once you point it out, it does make sense to me that that should work. Have you tested a configuration like this and confirmed that a Wii will still connect? I ask only because it also made complete sense to me that I should be able to completely turn off 802.11b and still have a Wii that's advertised as an 802.11g continue to work. I found out I was making a wrong assumption only after announcing that we'd be ending 802.11b support, only to have to roll back to make wii's continue to work.

Re: [WIRELESS-LAN] Wii U
I was wondering the same thing. I find the 802.11b/g/n reference on Nintendo's tech-specs page. They make no mention, though, about whether they've done a better job this time compared to the original wii which listed 802.11b/g wireless, but can only connect to 802.11g if it finds 802.11b first. I was also wondering about how the wireless controllers connect back to the main unit. I'm not finding anything on nintendo's site about that, but found that the wikipedia page about the Wii U links to a forum at http://www.neogaf.com/forum/showthread.php?p=42272901 . This shows what I think is the back of the controller that shows that it uses 5150-5250Mhz. That puts it on top of the low end of the 5Ghz channels used by WiFi. So, I suspect, but I don't know that this will cause interference with 5Ghz 802.11N service that's running on those channels. There's always another source of interference to make it harder to provide reliable wireless service in a college residence hall.

Re: [WIRELESS-LAN] wireless printers in dorms
I wasn't intending to suggest a policy banning 2.4Ghz or saying that I wanted to stop offering service in that band. Just thinking out loud of a policy that we'd make our best effort to make 2.4Ghz work, but 5Ghz would be the better performing more reliable networkI guess though, policy or not that's already how things are working out due to the nature of both bands and Rogue consumer devices. Also I suppose short of banning 2.4Ghz, it's hard to get student's attention to get them to buy 5Ghz capable computers, but I agree banning 2.4Ghz would cause many complaints. Does anyone have methods that you've used that have been successful in educating students to make the choice to spend a few extra dollars for dual band wireless when they're purchasing a new laptop?

Re: [WIRELESS-LAN] wireless printers in dorms
Has anyone declared 2.4Ghz hopeless and made a policy declaring that users that want a working well performing wireless network connection need to make arrangements to connect to the 5Ghz network? If a policy like that could fly, then it would be easier to run a 5Ghz network with great performance for all of the laptops to connect to. 2.4Ghz could become a best effort waste land polluted by all of the printers with their rogue ssid's, slowed down by the wii's that insist on making 802.11B connections before they'll make 802.11G connections, interfered with by the bluetooth, wifi-direct, etc. Of course, I guess this is only a good idea until 5Ghz becomes the new 2.4Ghz. I suppose it's probably only a matter of time until devices like printers have dual band radios and can cause 5Ghz problems too.

Re: [WIRELESS-LAN] WiFi Quality Monitoring
Does 7Signals have any competitors out there? Certainly wireless gear has sensing capabilities, and there are some dedicated sensors out there, but that's all got an IDS focus to it. As I look around I don't see anyone else that's monitoring the wireless network and its performance from the point of view of a wireless client.

blank ssid and mac address with unregistered vendor code
I'm seeing several rogue networks in our residence halls that are not like others I've seen before. They have these characteristics: - BSSID has a mac address that has a vendor code that doesn't exist when I try to look it up. - The SSID is type infrastructure - They are mostly 2.4ghz but I see one that's 5ghz - As long as I'm making correct assumptions, I believe I see them both from our Xirrus equipment and our HP MSM equipment. Xirrus reports the SSID as "(blank)" and HP reports it as "??" I take that to mean that there is no SSID name being broadcast. The HP and Xirrus equipment are in different buildings so I can't see the same rogue network from both types of equipment to compare. I'm wondering if anyone has seen networks like this before, and knows what sort of device might be creating them. -- Adam Forsyth Director of Network and Systems Luther College Library and Information Services 700 College Drive Decorah, IA 52101 563-387-1402 ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Aruba vs HP vs Meraki
Ethan, We've used Procurve access points for about 6 years now. We still have quite a few 420's in service though we're starting to move them out of service, and have a bunch of RP210's connected to a WESM controller. I had been holding out on deploying any of the MSM (Coloubris) access points because there wasn't a way to make them work with Bradford Campus Manager. This problem is supposed to be solved between the latest release of the controller firmware. I hope to set up a proof of concept of the two working together, and assuming that all looks good will probably deploy several MSM 422's this summer. I tried a few Meraki's about 3 years ago in an attempt to provide outdoor wireless to several of our sports fields. They found each other and magically made a mesh just like they were supposed to. If I configured them as a wide open wireless network I never had any trouble connecting to it. When I made an account in Meraki's cloud controller (I don't think they called it that yet) we had fairly mixed luck with getting that to work. Sometimes it'd work sometimes it'd time out. I see that they don't make that model of AP any more, and that they've made quite a few changes to their controller, so maybe that experience is irrelevant what currently happens. It seemed like a nice idea in principle, but in practice I just couldn't make it work for us.
